To @ZZ whom it may conce/rn:

Be it known that I, BnNJAMiN Gussii'r'rm, citizen of the United States,residing at iVard Springs, in the county of Todd and State of Minnesota,have invented certain new and useful Improvements in lagon- Brakes, ofwhich the following is a specilication.

The present invention relates to certain new and useful improvements inwagon brakes, and has for its object to provide a device of thischaracter which embodies` novel features of construction whereby thebrake is automatically applied when the draft animals pull rearwardlyupon the neck yoke, thereby eliminating the necessity for manuallyapplying the brake.

A further object of the invention is to provide an automatic brake ofthis character which is peculiarly constructed so that the brake isrendered inoperative when the vehicle is backed.

i/Vith these and other objects in View, the invention consists incertain novel combinations and arrangements of the parts as will morefully appear as the description proceeds, the novel features thereofbeing pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing dcscription and accompanyingdrawings, in which y Figure l is alongitudinal sectional view of a vehicle provided with an automaticbrake constructed in accordance with the invention, portions beingbroken away and removed. Fig. 2 is a top plan View of the rear portionof the running gear, showing the manner` of mounting the brake lbeam andbrake levers thereon. Fig. 3 is an enlarged sectional view on the line3-3 of Fig. 2, the brake shoe being indicated by dotted lines in theposition assumed when the vehicle is backed. Fig. 4 is a detailsectional view on the line 4 /l of Fig. 3. Fig. 5 is a detail View ofthe clamping block which is applied to the looped rear end of the cable.Fig. (i is a vertical longitudinal sectional VView through the tip atthe forward end of the wagon tongue. Fig. 7 is a plan view of the tip atthe forward end of the wagon tongue. Fig. 8 is an enlarged transversesectional view on the line 8 8 of Fig. G, and Fig. 9 is a detail view ofthe neck yoke.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, the character .l designates the runningI gearof a wagon, B the wagon body, and C the tongue, the said parts being allof the usual or conventional construction and the running gear Aincluding a reach l. A transversely disposed brake beam 2 is rigidlymounted upon the reach l. at a point slightly in advance of the rearwheels El. A brake lever il is pivotally mounted at a point between itsends, as indicated at 5, upon each end of the brake beam Q. The innerarm of each of the brake levers lis loosely received within a keeper (3upon the brake beam 2, while the outer arm of each of the leversoperates within a keeper 7 upon the brake beam 2.

'lhe outer end of each of the brake levers lcarries a brake .shoe Swhich is adapted to be brought into engagement with the rear wheel 3 soas to check the forward movement of the vehicle in the usual manner. Thebrake shoe 8 is shown as dove-tailed at f) into a brake block 10, therear face of the brake block having a bearing plate ll applied thereto.This bearing plate l1 serves to loosely engage the cross bar of a Ushaped link 12 by means of which the brake block is loosely mounted uponthe brake lever ll. The extremities of the U shaped link 1Q are extendedoutwardly at l2 and pivotally mounted within bearings 13 which areapplied to the brake lever. A flexible spring strip la serves to engagethe brake block 10 to hold the same yieldingly in an operative position,one end of the spring strip being secured at 15 to the brake lever ll,while the opposite end thereof is inserted in the dovetail joint E)between the brake block l() and the brake shoe 8. flfastening melnbers16 which pass through the brake block 10 serve to secure the bearingplate ll and the brake shoe 8 to the brake block, one ol the saidfastening members also engaging the end of the spring 141-. By pullingthe inner end of the brake lever flforward the rear end of the saidbrake lever is moved r nirwardiy so as to bring the brake shoe 8 intoengagement with the rear wheel 3. When the vehicle is moving in aforward direction, the brake shoe S will be swung downwardly until thepivot link '12 engages the brake lever l and has the swinging movementthereof checked. The brake shoe will then act upon the wheel to impedeand check the movement of the the aetion of the yielding means to throwthe brake shoe into operative position.

2. A wagon brake including a brake beam adapted to be applied to theWagon reach, brake levers pi votally mounted between their ends uponopposite ends of the brake beam, brake shoes carried by the outer endsof the brake levers, a slide mounted upon the brake beam under the innerends of the brake levers, projections upon the slide loosely engagingopposite sides of the inner ends of the brake levers, a guide rod projeeting Jfrom the brake beam and loosely engaging the slide, a springsurrounding the guide rod and engaging the slide for moving the same inone direction to move the friction shoes into an inoperative position,and means for moving the slide against the action of the spring to throwthe brake shoes into Operative position.

3. A wagon brake including a brake beam adapted to be applied to thewagon reach, brake levers pivotally mounted between their ends uponopposite ends of the brake beam, brake shoes carried by the outer endsof the brake levers, keepers upon the brake beam for receiving the endsof the brake levers and limiting the movement thereon, a slide n'iountedupon the brake beam under the inner ends oil the brake levers, one endof the slide being dellected laterally and provided with a guideopening, projections upon the slide engaging opposite sides of the innerends oi the brake levers, a guide rod pro jeeting from the brake beamand passing loosely through the guide opening' of the slide, a springsurrounding the guide rod and engaging the slide 'for moving the same inone direction to swing the brake levers and bring the brake shoes intoan inoperative position, and n'leans 'lior moving the slide against theaction of the spring to throw the brake shoes into an operativeposition.

In testimony whereof l allix my signature in presence of two witnesses.

BENJAMIN GUSSETTIE.
